Reaction Steps

According to Scheme 5 Step 3: A solution of 4-(1-(4-methoxybenzyl)-1H-pyrazol-4-yl)-2-(pyridin-2-ylamino)thiazol-5-carbonitrile (0.93 mmol, 360 mg) in TFA (3 mL) was microwaved for 5 min at 140° C. The reaction mixture was neutralized with a saturated solution of Na2CO3 (40 mL) and water (50 mL). The aqueous phase was filtered to afford a brown solid which was recrystallized thrice with DMF/water to yield 4-(1H-pyrazol-4-yl)-2-(pyridin-2-ylamino)thiazol-5-carbonitrile (0.24 mmol, 65 mg, 26%) as an off-white solid.
